Yes it is. The solution is: y=4 .
No. -4 does not equal -2(1).
(4.25, 0.25) is a solution.
Possibly the solution to an equation
Given: x + y = 5 2x + y = 6 We can subtract the second equation from the first to get: -x = -1 x = 1. From there, substituting back in to the first equation yields: 1 + y = 5 y = 4. The solution is (1, 4).
x = 0 and y = 4
Yes it is. The solution is: y=4 .
If for example: 4y = 16 Then: y = 4
No. -4 does not equal -2(1).
y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
(4.25, 0.25) is a solution.

It is a simultaneous equation and its solution is x = -1 and y = -5
Oh, dude, that's like super easy. So, to find y, you just divide both sides by 5, and you get y = 7. Boom, equation solved! Math is like a piece of cake, right?
The equation 6 + y = 12 is a simple equation in one variable. If you add 6 to both sides of the equals sign, you get y = 18, and that is the solution.
You have one equation in two unknowns. There is no solution possible without a second (independent) equation in the same two unknowns.
